Well..
How long's a piece of string
I've just gone through some shots I took in Pompey and RGB'd em in Photoshop to see what variations I could get. The colour off Daves chart looks very similar to how the colour looks in shade but as soon as light hits it, you're looking toward pure white in some cases and I didn't go for those bits! Here are a selection..
Intrepid/Fearless - neutral but in sunlight - 176, 173, 166
Ark Royal - shade/out of direct sunlight - 130, 139, 144
Mine Hunter 'unknown' - side/direct sunlight - 233, 231, 219
Mine Hunter 'unknown' - Bow/direct sunlight - 219, 216, 207
Bristol - side/direct sunlight - 221, 220, 215
Bristol - Bow/natural shade from bow shape - 181, 181, 179
Bristol - Stern/direct sunlight - 207, 204, 199
None of the points taken indicating direct sunlight were parts that were highlighted by the sun but what the above DOES highlight is that the inboard or in shade colours are vastly different from the lit side.. nothing odd here but as the colours are all the same, they do look a lot different (it makes sense to me anyway)
To highlight how the 'correct' colour (160,176,176) sits in the grand scale of things and how ships look in real life, here is an example of that colour dotted 5 times on a modern destroyer..
